ATTORNEY Patented Mar, 19, 1940 w PATENT OFFICE 2.1mm wumow cons'muo'non Harry I. 'Bader, 'l'roy, Ohio, usignor to The Troy Sunshade Company, Troy, Ohio, a corporation of Ohio Application June a, 1m, Serlal No. 212.419

This invention relates to windows and more particularly to guiding and supporting means for sliding windows.

One object of the invention is the provision 5 of a window construction affording a weathertight mounting for a slidable window sash in a window frame, so arranged as to hold the sash against play or movement in. the window frame but requiring the exertion of only a comparatively small forceto open or close the window.

Another object of the invention is the provision of a window construction of the character mentioned in which the window sash is guided for movement in a rubber guide channel which is diate ribs affording a limited area of engagement with the sides of the sash, the outer ends of the legs of the channel terminating in outwardly extending flexible sealing portions engaging the sash.

Other objects and advantages of the invention will be apparent from the following description, the appended claims, and the accompanying drawing, in which:

Fig.1 is a front elevation of a window construction embodying the present invention;

Fig. 2 is an end view of one of'the upwardly extending channel portions of the window frame;

Fig. 3 is a horizontal section taken on the line 30 35-3 of Fig, 2;

Fig. 4 is a horizontal section taken on the lin 3-8 of Fig. 2;

Fig. 5 is an enlarged cross sectional view of the rubber guide channel; and

Fig. 6 is an enlarged front elevation of an upper corner of the window.

The construction as herein shown is particularly adapted for bus windows and the like, in which one of the window sashes is adapted for 40 sliding movement in laterally spaced frame portions. Referring to the drawing by reference numerals, i designates the stationary frame structure of a bus or other construction in which the window is arranged, this frame structure including upwardly extending channel portions ll, one of which is shown in Fig. 2, at opposite sides of the window opening. Suitably secured in the lower portion of the window opening is a stationary window l2, while l3 represents the slidable 50 tion of the window opening and preferably arranged to operate in a plane outside of the lower window l2.

The channel portion H or post is preferably of sheet steel construction providing an outer provided with longitudinally extending intermewindow sash forming a closure for the upper por- (cl. zoo-44.5)

channel I! and an inner channel l6 for the upper and lower windows respectively. 'I'helowr window l2, as shown, comprises a glass panel having a marginal glazing strip ll of any suitable material, preferably of a resilient character where it extends along the vertical edges of the glass, holding the glass panel in the channel it. The upper side of the marginal frame is preferably I provided with a flexible rubber rain or drip strip i8 held in place by a metal channel i8 and pressing against the inner side of the bottom of the upper sash. The bottom edge ofv the glass is suitably connected to a rubber edging strip i9 which seals against the lower portion of the window opening in the bus frame structure. The slidable sash i3 comprises a glass panel which is preferably although not necessarily provided with a marginal sheet metal'frame 2! in which the edges of the glass. panel are received and retained as by means of suitable cementitious material as indicated at 22. Upper andlower horizontally extending portions 23 of the marginal frame connectwith the vertically extending portions 24 As shown in Figs. 2 and 6 screws 25 secure, the lower portion 23 to the wooden insert 24" provided in the vertically extending portions 24.

Received in each ofthe vertically extending channels 15 of the window frame is a resilient guide channel 26 which in turn receives the mar-, ginal frame of the window sash Hi. This guide channel 26 is an integral yielding rubber member extending'from the top to the bottom of the channel It, the rubber composition being of such. character as to aflord a comparatively low coefficient of friction so that the sheet metal marginal frame il of the sash can be readily moved without undue gripping between the-metal and the rubber. As will be apparent from Figs. 3, land 5, the rubber guide channel 26 comprises a web 'fiortion 21 integrally formed with laterally spaced sides or legs 28, each of which terminates in an outwardly extending tapering flexible sealing portion 29 adapted to presslightly against the side .of the sash and seal the sash against rain, dust,, etc;

, Each leg 28 is also provided with a longitudinally extending rib 30 which is adapted to bear yieldingly against the side of the marginal frame 2! and locate the latter in'a centered position, the rib 30 serving to space the sides of the marginal frame 2i from the adjacent portions of the legs 28 so that, the'frame 2| is centered mainly by the ribs 30 and to a considerably smaller degree by the sealing portions29. The outer side of each leg 23 is provided with a longitudinally extending recess 3| opposite the location of the rib 30 so that when the rubber channel, which has a cross sectional form as shown in Fig. 5

when unconfined, is applied to the channel I 5 and the outer portions of the legs are forced towards one another, an air space 32 will be provided adment with the sides of the marginal frame 2i.

As the sash i3 is raised or lowered, the ribs 30 provide the major restraining force preventing lateral movement of the sash transversely to the plane of the sash, and as the area of engagement of the rubber guide channel with the marginal frame 2| is quite small as compared with the area of the marginal frame within the confines of the rubber guide channel it will be apparent that the friction between the metal marginal frame and the rubber is quite small so that the sash may be held against play or vibration in its mounting while requiring only a very small force in excess of the weight of the sash'itself to raise the sash. The extending sealing portions 29 exert only a comparatively small force against the sides of the marginal frame 2i, since they extend outwardly at an angle and can flex outwardly to conform to and engage the sides of the sash, but are effective in preventing the entrance of rain, water, dust, etc. I Arranged between each side end of the window sash and the rubber guide channel in which it is guided is a rigid strip 33, preferably a flat sheet metal strip about as wide as the peripheral frame 2|, this strip being held by a plurality of securing screws 35 which extend through the rubber web 2'! and through holes in the channel l5, these screws also acting to hold the webs 27 crime rubber guide channels against the inner surfaces of the channel iii. The heads of the screws are countersunk in the strip 33 so as to be flush with the surface of the strip that is presented to the marginal sash frame. of the peripheral frame 2i of the movable sash are thus guided against metal portions and are prevented from engaging or digging into the rubber of the channel portions 21, these metal strips 33 also acting to reduce the rubbing friction at the ends of the marginal frame when the sash is raised or lowered.

As herein shown, the upper horizontally extending portion 23 of the slidable window is provided with a slidable arm-35 which is connected to a latching tongue 36 which is inwardly offset so as to project into the channel l6 and engage a latch strip 31 which is provided with a series of steps 38, and which is spot-welded or otherwise connected to the upper portion of the channel it above the top of the lower stationary sash. The lower sash is preferably held in its lowermost position by means of a metal strap 39 at each end of the frame, each strap 39 extending laterally into the channel i8, and attached by a bolt 43 which is screwed into the channel IS. A suitable sealing closure is provided for the top of the sash l3 as by means of a strip ll of felt or the like.

While the form of apparatus herein described constitutes a preferred embodiment of the invention, it is to be understood that the invention is The ends not limited to this precise form of apparatus, and that changes may be made therein without departing from the scope of the invention which is defined in the appended claims.
